Description

Technical Field

[0001] This invention relates to the field of reverse osmosis technology, specifically to a reverse osmosis device for green hydrogen, water saving, and energy saving. Background Technology

[0002] As the global energy structure transitions towards a cleaner and lower carbon profile, green hydrogen, as a key zero-carbon energy carrier for achieving the "dual carbon" goal, requires a large amount of high-purity water for its production. In order to obtain high-purity water, reverse osmosis equipment is needed to purify the water through reverse osmosis membrane technology.

[0003] Reverse osmosis technology is currently the most core and widely used pre-desalination process for producing ultrapure water. It uses a high-pressure pump to apply pressure to raw water (such as tap water or groundwater), forcing it to pass through a reverse osmosis membrane, thereby effectively removing most dissolved salts, colloids, microorganisms, and organic matter. However, in order to ensure that reverse osmosis wastewater meets discharge standards, it is necessary to remove heavy metal ions. Existing reverse osmosis wastewater treatment methods often employ biological methods, chemical precipitation methods, and adsorption methods.

[0004] The existing chemical precipitation method for treating reverse osmosis wastewater involves first filtering impurities from the wastewater using filter plates, then adding an appropriate amount of chemical precipitant to the wastewater. The precipitant reacts with heavy metal ions in the wastewater to form a precipitate, which is then allowed to settle to the bottom. Finally, the treated wastewater is extracted. However, this precipitation separation method is time-consuming, and the wastewater and the separated precipitate require additional processing, increasing labor costs and reducing the efficiency of the reverse osmosis equipment. At the same time, impurities in the reverse osmosis wastewater can easily clog the filter plates, preventing them from effectively filtering impurities and thus affecting the treatment effect of the reverse osmosis equipment.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figures 1-2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the present invention is a reverse osmosis device for green hydrogen water saving and energy saving, including a treatment tank 1 for wastewater sedimentation. The inside of the treatment tank 1 is provided with a first filter plate 2 and a second filter plate 3 from bottom to top. A driving mechanism is fixedly provided inside the treatment tank 1. Two horizontal plates 4 are fixedly connected from top to bottom inside the treatment tank 1. A first guide rod 5 is slidably connected to the upper side of the upper horizontal plate 4. A circular plate 6 is fixedly connected to one side of the first guide rod 5. A clearing rod 7 for clearing the first filter plate 2 is arrayed on one side of the circular plate 6. A spring 8 is fixedly connected between the circular plate 6 and the horizontal plate 4. A second guide rod 9 is slidably connected to the lower side of the upper horizontal plate 4. A disc 10 is fixedly connected to one side of the second guide rod 9. A squeezing block 11 for sediment discharge is fixedly connected to the lower center of the disc 10. A spring 12 is fixedly connected between the disc 10 and the horizontal plate 4. A sediment discharge outlet 13 is opened through the middle of the bottom of the inside of the processing tank 1. A pipe 14 communicating with the sediment discharge outlet 13 is fixedly connected to the lower side of the processing tank 1. An inclined arc surface 41 is opened on the upper side of the disc 10. It can be explained that the inclined arc surface 41 on the disc 10 allows heavier sediment to roll downwards and be concentrated at the bottom of the inside of the processing tank 1 for sediment discharge. The squeezing block 11 is adapted to the sediment discharge outlet 13 and the pipe 14 so that the squeezing block 11 can squeeze the sediment out, which is convenient to use. The other side of the first guide rod 5 and the second guide rod 9 respectively penetrate through the two horizontal plates 4 and extend to the corresponding side of the horizontal plates 4, allowing the two guide rods to move up and down.

[0021] In this embodiment, please refer to Figures 1-2 , Figure 3 as well as Figure 5 The drive mechanism includes a mounting box 15 fixedly connected to the inner wall of the processing tank 1. A first gear 16 is provided inside the mounting box 15. A servo motor is fixedly connected to the outer surface of the processing tank 1. The output shaft of the servo motor passes through the processing tank 1 and extends into the interior of the mounting box 15. The output shaft of the servo motor is fastened to the first gear 16. Two first racks 52 distributed vertically are respectively meshed at both ends of the first gear 16. The servo motor is existing technology and is not limited in this embodiment.

[0022] Both ends of the mounting box 15 have T-shaped grooves 17. Each of the two T-shaped grooves 17 has vertically distributed limiting blocks 18 slidably connected inside. One side of each limiting block 18 is fastened to one of the two first racks 52. A vertical rod 19 is fixedly connected to the lower side of the first rack 52. One side of the vertical rod 19 passes through the mounting box 15 and extends to the lower side of the mounting box 15. A first bending frame 20 is fixedly connected to one side of the vertical rod 19. It can be noted that the limiting blocks 18 can move up and down in the matching T-shaped grooves 17 to limit and guide the movement trajectory of the two first racks 52, ensuring that the two first racks 52 move and adjust smoothly and safely.

[0023] Another first rack 52 is fixedly connected to the upper side of a vertical rod 19. One side of the vertical rod 19 passes through the mounting box 15 and extends to the upper side of the mounting box 15. A second bending frame 21 is fixedly connected to one side of the vertical rod 19. The first bending frame 20 and the second bending frame 21 are symmetrically arranged. The first bending frame 20 is located above the second guide rod 9, and the second bending frame 21 is located below the first guide rod 5. It can be noted that the first bending frame 20 and the second bending frame 21 can correspond to the two guide rods respectively, and are used to drive the unblocking rod 7 to unblock the first filter plate 2 and drive the disc 10 and the extrusion block 11 to extrude the sediment, so that the sediment can be discharged quickly and the treatment efficiency of reverse osmosis wastewater can be improved. The reverse osmosis equipment is an indispensable device in the green hydrogen production line, ensuring that the entire process of green hydrogen production meets the high standards of green and sustainable development.

[0024] For details, please refer to Figures 3-5 After the sedimentation process is completed, the servo motor is started, and the output shaft of the servo motor drives the first gear 16 to rotate. In this way, the two first racks 52 at the first gear 16 will move up and down respectively. One of the first racks 52 drives the vertical rod 19 and the first bending frame 20 to move downward, so that the first bending frame 20 squeezes the elastic disc 10 and the squeezing block 11 to move downward, thereby squeezing the sediment down and concentrating it. The other first rack 52 drives the vertical rod 19 and the second bending frame 21 to move upward. At this time, the second bending frame 21 squeezes the elastic disc 6 and the unblocking rod 7 to move upward, so that the unblocking rod 7 unblocks the first filter plate 2, thereby improving the subsequent filtration effect of the first filter plate 2. As the first bending frame 20 moves downward, it drives the two bending rods 51 and the fixing block 28 to move downward together. The moving second rack 30 drives the second gear 27 at the rotating shaft 23 to rotate, causing the sealing cover 25 to flip downward and move away from the pipe 14. At this time, the disc 10 and the squeezing block 11 push the accumulated sediment from the sediment discharge outlet 13 to the pipe 14, thereby quickly discharging the sediment and improving the treatment effect of the reverse osmosis equipment. In this embodiment, the drive mechanism can also synchronously drive the sealing cover 25 to flip, realizing sediment discharge. It has the function of multiple uses, which not only reduces costs, but also has higher stability and synchronization.

[0025] In this embodiment, please refer to Figure 5 and Figure 7 A base plate 22 is fixedly connected to the lower side of the processing tank 1. A rotating shaft 23 is rotatably connected inside the base plate 22. A mounting block 24 is fixedly connected to the outer surface of the rotating shaft 23. A sealing cover 25 located below the pipe 14 is fixedly connected to one side of the mounting block 24. A rubber gasket 26 for sealing the pipe 14 is fixedly connected to the upper side of the sealing cover 25. One side of the rotating shaft 23 passes through the base plate 22 and extends to one side of the base plate 22. A second gear 27 is fixedly connected to one side of the rotating shaft 23. Bending rods 51 are fixedly connected to both ends of the first bending frame 20. A fixing block 28 is fixedly connected between the two bending rods 51. The fixing block 28 is located below the sealing cover 25. A connecting plate 29 is fixedly connected to one side of the fixing block 28. A second rack 30, which meshes with the second gear 27, is fixedly connected to one side of the connecting plate 29. It can be explained that the rubber gasket 26 on the sealing cover 25 can tightly fit the sealing pipe 14 to prevent leakage from the pipe 14. At the same time, when the output shaft of the servo motor drives the first gear 16 to reverse, the two first racks 52 can drive the first bending frame 20 and the second bending frame 21 to reset. At this time, the bending rod 51 can move upward, allowing the second rack 30 to drive the second gear 27 to rotate. In this way, the sealing cover 25 can rotate upward, allowing the rubber gasket 26 on the sealing cover 25 to enter the interior of the pipe 14 to seal the pipe 14, so as to seal the sediment discharge outlet 13 of the treatment tank 1 after the sediment discharge is completed.

[0026] Example 2 Based on Example 1, please refer to Figure 4 The inner wall of the treatment tank 1 has two symmetrically arranged grooves 42. Two water outlet boxes 39, communicating with the grooves 42, are fixedly connected to the outer wall of the treatment tank 1. A drain pipe 40, communicating with the water outlet box 39, is fixedly connected to the lower side of each water outlet box 39. An embedding groove 43 is formed on the upper side of each water outlet box 39. One side of the embedding groove 43 penetrates the water outlet box 39 and extends to the bottom of the inside of the water outlet box 39. A sealing plate 44 is slidably connected inside each of the two embedding grooves 43. The second bending frame 21 has one side... Two symmetrically arranged bent rods 45 are fixedly connected, and the upper sides of the two sealing plates 44 are respectively fastened to the two bent rods 45. It can be explained that when the output shaft of the servo motor drives the first gear 16 to reverse, the two first racks 52 can drive the first bending frame 20 and the second bending frame 21 to reset. At this time, the bent rods 45 can move down, allowing the two sealing plates 44 to re-enter the interior of the two embedded grooves 43, so as to seal the groove 42 and the water outlet box 39 and cut off the discharge of wastewater.

[0027] Please see Figures 2-3 as well as Figure 6The inner wall of the treatment tank 1 is connected to a support plate 31. The upper side of the support plate 31 is fixedly connected to a slide rail 32. A slider 33 adapted to the slide rail 32 is slidably provided on the slide rail 32. One side of the slider 33 is fastened to the first filter plate 2. The upper side of the first filter plate 2 is connected to a top plate 37. The upper side of the top plate 37 is fastened to the second filter plate 3.

[0028] A top block 34 is fixedly connected to the upper side of the slider 33. A guide groove is provided on one side of the top block 34. A telescopic block 35 is slidably connected to one side of the guide groove. A spring 36 is fixedly connected between the telescopic block 35 and the top block 34. It can be explained that when the first filter plate 2 needs to be installed, the four sliders 33 can be placed on the slide rail 32, and then the elastic telescopic blocks 35 are pressed in sequence to limit the telescopic blocks 35 so that the sliders 33 can drive the first filter plate 2 and the second filter plate 3 into the interior of the treatment tank 1, and are used to limit the movement at the four support plates 31 to ensure the stability of the first filter plate 2 and the second filter plate 3 during use.

[0029] Please see Figures 8-9 The upper side of the second filter plate 3 is connected to a vertical plate 46. The upper side of the vertical plate 46 is fixedly connected to a first conical seat 47 that runs vertically through the center. The interior of the first conical seat 47 is engaged with a second conical seat 48 that runs vertically through the center. The interior of the second conical seat 48 is fixedly connected to two inverted V-shaped plates 49 that are distributed vertically. One side of each of the two inverted V-shaped plates 49 is provided with a through transverse groove 50. It can be explained that the wastewater enters only to the middle of the two inverted V-shaped plates 49. In this way, the two inverted V-shaped plates 49 and the transverse grooves 50 on the inverted V-shaped plates 49 can divert the wastewater entering the treatment tank 1, so that the wastewater flows evenly to the first filter plate 2 for better filtration. The first conical seat 47 and the second conical seat 48 prevent the wastewater from splashing out. At the same time, the second conical seat 48 can be disassembled by means of a snap-fit ​​for cleaning. The operation is simple and convenient.

[0030] The filter pore diameter of the second filter plate 3 is larger than that of the first filter plate 2. The first filter plate 2 and the second filter plate 3 are used to filter reverse osmosis wastewater. The outer wall of the treatment tank 1 is fixedly connected to the inlet pipe 38, which is connected to the treatment tank 1. It can be noted that the second filter plate 3 can filter larger impurities, while the first filter plate 2 can filter smaller impurities, so as to achieve multiple filtration and improve the treatment effect of the reverse osmosis equipment. Furthermore, flocculants and chemical precipitants can be added into the treatment tank 1 through the inlet pipe 38 to facilitate the precipitation reaction. In the preparation process of green hydrogen, the reverse osmosis equipment plays a working role in preparing the ultrapure water required for water electrolysis.

[0031] In use, this invention involves injecting reverse osmosis wastewater into treatment tank 1. The wastewater then passes sequentially through the first filter plate 2 and the second filter plate 3 for initial filtration of impurities. Once a certain height is reached, flocculant and chemical precipitant are added to treatment tank 1, causing heavy metal ions in the wastewater to precipitate. After precipitation, a servo motor is activated, causing its output shaft to drive the first gear 16 to rotate. This allows the two first racks 52 at the first gear 16 to move up and down respectively. The first racks 52 then drive the vertical rod 19 and the first bending frame 20 downwards, causing the first bending frame 20 to compress the elastic disc 10 and the compression block 11 downwards. This compresses the precipitate, causing it to fall and concentrate. Meanwhile, another... The first rack 52 can drive the vertical rod 19 and the second bending frame 21 to move upward. At this time, the second bending frame 21 can squeeze the elastic circular plate 6 and the unblocking rod 7 to move upward, so that the unblocking rod 7 can unblock the first filter plate 2, thereby improving the subsequent filtration effect of the first filter plate 2. Then, as the first bending frame 20 moves downward, it drives the two bending rods 51 and the fixing block 28 to move downward as well. The downward moving second rack 30 can drive the second gear 27 at the rotating shaft 23 to rotate, so that the sealing cover 25 flips downward and moves away from the pipe 14. At this time, the disc 10 and the squeezing block 11 can push the accumulated sediment from the sediment discharge outlet 13 into the pipe 14, so as to quickly discharge the sediment and improve the treatment effect of the reverse osmosis equipment. As the second bending frame 21 moves upward, it also drives the two bending rods 45 to move upward together. This moves the two sealing plates 44 away from the two embedded grooves 43, allowing the two outlet boxes 39 to open. Then, the treated reverse osmosis wastewater can enter the interior of the outlet box 39 along the groove 42 and then be discharged along the two drain pipes 40 until all the wastewater is treated. At the same time, the drive mechanism in the reverse osmosis equipment can simultaneously realize the wastewater discharge, sediment discharge and filter plate unclogging steps. This mechanism saves costs, has the effect of saving water and energy, and improves the working efficiency of the reverse osmosis equipment in treating reverse osmosis wastewater. After the unblocking rod 7 clears the first filter plate 2, the second bending frame 21 continues to move upward, causing the circular plate 6 to move the first filter plate 2 and the second filter plate 3 upward. At this time, the slider 33 at the first filter plate 2 moves along the slide rail 32, allowing the first filter plate 2 to move and adjust smoothly. Then, when the second bending frame 21 is in place, the compressed elastic telescopic block 35 can be released. In this way, the four elastic telescopic blocks 35 can extend and rest on the four slide rails 32 to remove the first filter plate 2 from the inside of the processing tank 1. When the second bending frame 21 is reset, the first filter plate 2 will not be affected, so that it is convenient to clean the impurities on the first filter plate 2 and the second filter plate 3 in the future, thereby improving the overall work efficiency and ease of operation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
